Say goodbye to being pen-less with this on your keychain. (However, it might be pointed out that you’d still have to search around for your keys to get to the pen. Also, if you want to see the pen ‘in action’ there’s a dumb video showing just how convenient it can be.)

The ultra-compact TelePen is a handy collapsible pen that attaches to your keychain. Weighing less than an ounce and measuring less than two inches, you’ll hardly notice the diminutive telescoping pen dangling from your keyring.But the TelePen is there when you need it, expanding to nearly the length of a standard pen. Its tough stainless steel exterior protects it from the elements. Includes three black ink refills.
